and sandstone below) and 2nd White Sandstone (F coal and sandstone below) are • <br /> monitored at seven locations. The Lewis Shale is monitored at one location. The Johnson <br /> and Pyeatt Gulch alluvial aquifers are monitored at one site in each of these drainages <br /> while the Flume Gulch alluvium is monitored at two locations. The 1998 hydrologic <br /> monitoring report, Hydro-Engineering, LLC (1999), presents the discussion of the <br /> monitoring results through 1998. The table on the pull-out index provides basic well data <br /> for all wells monitored in 1999. <br /> Springs at Trapper Mine were monitored during 1999 in accordance with the <br /> approved monitoring plan. Springs with measured flows of greater than 5 gpm were <br /> sampled for full suite water quality parameters. Results of the 1999 spring monitoring are <br /> presented in Table B-2. <br /> Table 1-1 (page 1-4) presents the pit and well dewatering data and volume of • <br /> water used for dust depression for Trapper Mine for 1999. This data shows that, on an <br /> average, approximately 45 gpm was pumped from the Trapper Mine pits during 1999. No <br /> well dewatering was done in 1999. The average pit pumping rates were 25 and 21 gpm <br /> for the D and F pits, respectively. This data is useful in interpreting water-level changes <br /> and consumptive use. No pumping occurred in the A pit during 1999. <br /> Surface-water flow and quality were monitored at only Flume Gulch (S-1), <br /> Johnson, No Name, Oak and East and West Pyeatt drainages during 1999. The Johnson, <br /> No Name, East Buzzard, Coyote, West Buzzard, Ute, Middle Pyeatt, Elk, East Pyeatt, Deer, <br /> West Pyeatt, Far East Buzzard, Grouse, Sage, Oak, West Flume and Middle Flume <br /> drainages are Trapper's NPDES discharge sites 001, 002, 003, 005, 006, 008, 009, 010, <br /> 011, 012, 013, 014, 015, 016, 017, 019 and 020, respectively. • <br /> 1-2 <br />
